Application filed September 30, 1904. Serial No. 226,680. (No model.)

T all whom, t 712/607/ concern.-

Be it known that I, NILs N. EGGE, a citizen of the United States,residing at Joice, in the county of Worth and State of Iowa, haveinvented a new and useful Draft-Equalizer, of which the following is aspecification.

rIhis invention relates to draft-equalizing devices, and is particularlydesigned for use in connection with harvesting-machines, so as to admitof the use of swingletrees of the usual size without interfering withthe reel of the machine.

A further object of the invention is to provide for readily changingfrom a four-horse evener to a three-horse evener, and vice versa, by avery simple arrangement of the device and without altering the mountingof the evener.

IV ith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described,shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacriiicing anyof the advantages of the invention.

In the accompanying drawings, Figure 1 is a perspective viewillustrating a draft-equalizer of the present invention mounted upon atongue or pole. Fig. 2 is a detail sectional view taken longitudinallythrough the inner end portion of the evener-bar. Fig. 3 is a detailsectional view taken on the line 3 8 of Fig. 1.

Like characters of reference designate corresponding parts in each andevery figure of the drawings.

The device of the present invention is supported upon a pole or tongue 1and includes an evener-bar 2, disposed transversely across the top ofthe pole and fulcrumed thereon adjacent its inner end by means of aremovable y bolt or fulcrum-pin 3. At the outer end of the evener-barthere is a clevis or other suitable device 4 for the connection of adrawbar, while the inner end of the evener-bar is provided with twolongitudinally-alined perforations 5 and 6. A brace-link 7 has one endapplied to the under side of the tongue or pole 1 and is pierced by thelower end of the bolt 3, so as to swing thereon, while its outer end isextended upwardly to engage the under side of the inner end portion ofthe evenerbar and is pierced by two openings 8 and 9, registered withthe openings 5 and 6 of the draw-bar.

Upon the inner end portion of the evenerbarQ' is supported a lever 10,which projects at the inner end of the evener-bar and is fulcrumedthereon by means of a removable bolt 11, passing through one of the twoopenings 12 and 13 in the lever and engaging in one of the pair ofregistered openings in the evenerbar and the link 7. A clevis or otherdevice 14 is carried by the inner end of the lever for the connection ofa suitable draw-bar. The outer end of the lever is guided by means of arod or bar 15, having its forward end bifurcated or forked, as at 16, soas to straddle the outer end of the lever 10, to which it is pivotallyconnected by means of a bolt 17, while its rear portion telescopeswithin a tubular member 18, fulcrumed or pivotally connected at its rearend to the top of the tongue or pole 1, as indicated at 19. Upon the rod15 is an adjustable clip 20, capable of being fixed upon the rod atdifferent points between the forward end of the tubular vmember 18 andthe fork 16, so as to form a stop for contact with the forward end ofthe member 18, and thereby limit the telescopic movement of the rodwithin the tubular member.

The arrangement of the device as shown in Figs. 1 and 2 of the drawingsis for four horses, one team being connected to the lever 10 with ananimal at each side of the pole, while the other team is connected tothe outer end of the evener-bar 2 through the medium of the clevis orconnection 4, the arrangement of the evener-bar and the lever 10beingsuch as to equalize the pull of the team connected to the outer endof the bar 2, and thereby apply the power of the combined teams directlyin line with the pole. It will here be explained that by the presentarrangement of the lever 10 having its inner end working over the centerof the pole the draft-animals which are IOO Y connected to the lever arelocated at opposite sides of the pole and adjacent the same, so as tosupport the pole in an effective manner, which is an important advantageover equalizing devices wherein all of the draft-animals are locatedremote from the tongue or pole, for in this latter arrangement the polehangs down close to the ground and is liable to strike obstructions.

To accommodate the device to three animals, the fulcrum-bolt 11 isshifted to 'the opening 13 of the lever and the openings 6 and 9 of theevener-bar 2 and the link 7, one animal being connected to the outer endof the evener-bar 2 and two animals connected to the lever l0. When thebolt 1l has been shifted inwardly, as described, the power of theevener-bar 2 is increased, while that of the lever 10 is decreased, theproportions of increase and decrease being suflicient to offset thegreater power applied by the team at the pole, thereby effecting adirect draft in alinement with the pole or tongue.

It will here be explained that the fulcrum of the evener-bar 2 is thebolt or pin 3, while the fulcrum of the lever 10 is its pivotalconnection with the rod 15, wherefore it will be understood that thefulcrums of the evenerbar and the lever are not shifted, but theconnection between the evener-bar and the lever is shifted, so as tovary the power of these members in accordance with the arrangement ofthe draft-animals.

Having fully described the invention, what is claimed isH4 1. In adraft-equalizer, the combination of an intermediately-fulcrumedevener-bar, a lever pivoted intermediate of its ends to the inner endportion of the evener-bar, a draft connection at the inner end of thelever, `and a fulcrum-support for the outer end of the lever consistingof an endwise-slidable member having a pivotal support.

2. In a draft-equalizer, the combination of an intermediately-fulcrumedevenerbar, a lever having an intermediate pivotal connection with theinner end portion of the evener-bar, said pivotal connection beingshiftable longitudinally of the lever and the bar, and a fulcrum-supportfor the outer end of the lever consisting of a slidable member having apivotal support for its rear end.

3. In a draft-equalizer, the combination of an intermediately-fulcrumedevener-bar having its inner end portion provided with a longitudinalseries of openings, a lever applied to the inner end portion of the barand provided with a longitudinal series of openings, a pivot device forinterchangeable engagement with the openings of the lever and the bar,and a fulcrum-support for the outer end of the lever consisting of aslidable member connected to the lever and having a pivotal support forits rear end.

4. In an equalizing device, the combination of anintermediately-fulcrumed evener-bar, a lever pivoted intermediate of itsends upon the inner end portion of the evener-bar and provided at itsinner end with adraft connection, a rod pivoted to the outer end of thelever, and a tubular member telescopically receiving the rod andprovided at its rear end with a pivotal support.
